from inside the box will have flown out through the wire meshes 

 into the field. At the end of twelve days the box should be 

 emptied by unscrewing the side piece, and the contents should 

 be buried in the ground taking special care not to allow any 

 green winged insect to escape out of the 'ox. If you see any green 

 winged insects kill them otherwise they will produce bollworms 

 in the field. 



Tne parasites spread rapidly in the fields where the parasite 

 boxes are used : from such fields the bollworm affected bolls 

 should be plucked and filled in more parasite boxes : these bolls 

 will have the parasites on the bollworms in them. These parasite 

 boxes should again be used as described above in other cotton 

 fields. In this manner the number of parasite boxes can be 

 rapidly increased and the parasite can be established in different 

 localities within a short period. 



NOTE. Parasite boxes can be had each year in the beginning of August by applying to the 

 Assistant Professor of Entomology. Agricultural College, Lyallpur. 



3. Cotton plants should not be allowed to remain in the 

 ground after the crop has been picked. Otherwise they will 

 afford shelter to the pest till the next season. 



4. Bhindi should not be grown near cotton fields otherwise 

 bollworms breeding in bhindi will go and attack cotton. But if 

 bhindi is grown the plants should be carefully examined and all 

 attacked flowers and fruits plucked off and destroyed so as not to 

 let the bollworms breed in them,
